Abstract

PROCEDIMIENTO PARA ELIMINAR OXIDOS DE NITROGENO DE LOS GASES DE COMBUSTION DE UNA PLANTA DE FABRICACION DE PULGA. PROCEDIMIENTO PARA ELIMINAR OXIDOS DE NITROGENO DE LOS GASES DE COMBUSTION DE UNA CALDERA DE RECUPERACION DE SOSA DE UNA PLANTA DE FABRICACION DE PULGA, EN DONDE, A LOS GASES DE COMBUSTION DE LA CALDERA DE RECUPERACION DE SOSA SE LES AÑADE EN PRIMER LUGAR UN AGENTE OXIDANTE, TAL COMO DIOXIDO DE CLORO U OZONO, QUE OXIDA EL OXIDO DE NITROGENO A DIOXIDO DE NITROGENO. POSTERIORMENTE, LOS GASES DE COMBUSTION SE LLEVAN A UN LAVADERO DE GASES DE COMBUSTION, DONDE SE INYECTA EN LOS GASES DE COMBUSTION UN REACTIVO PROCEDENTE DE LA CIRCULACION DE PRODUCTOS QUIMICOS DE LA PLANTA DE FABRICACION DE PULGA, REACTIVO QUE AL ENTRAR EN CONTACTO CON EL DIOXIDO DE NITROGENO REDUCE EL DIOXIDO DE NITROGENO A NITROGENO. EL GAS DE COMBUSTION QUE CONTIENE NITROGENO SE SACA DEL LAVADERO Y EL REACTIVO OXIDADO SE LLEVA DE NUEVO A LA LINEA DE CIRCULACION DE PRODUCTOS QUIMICOS DE LA PLANTA DE FABRICACION DEPULGA.
